missing network-manager applet randomly

[shantanu saha]

nm-applet disappear randomly. It happens when i logged in. Log out or nm-applet command load the indicator. This problem is random. It doesn't happen always. I have notices that if network manager failed to connect a wifi network in lightdm screen then it happens.
Not sure about the test case. I have two network with same name in office and home(neighbor). Sometimes system detect that network and try with office's password and failed to log in.
